The examples in the ac source Programming Guide are similar to the ones in this section, except that they use SCPI commands.

1 - Setting the Output Voltage Amplitude

NOTE: The maximum voltage that the ac source can output is limited by the peak value of the waveform, which is 425 Vpeak. Since the output is programmed in units of rms volts, the maximum value that can be programmed is dependent on the peak-to-rms ratio of the selected waveform. For a sinewave, the maximum ac voltage that can be programmed is 300 Vrms. For other waveforms the maximum may be different.

When you turn on the ac source, the default output shape is a 60 Hz sinewave at 0 Vrms. There is no output from the ac source because the default output state is OFF, as indicated by the Dis annunciator.

Set the output to 120 V rms as follows:

Action

You can set the voltage in any of three ways:

1.On the Function keypad, press Voltage. On the Entry keypad, press 1 2 0 Enter. This is the easiest way to enter an accurate value.

increment or decrement the existing value. This technique is useful when you are

 

 

 

making minor changes to an existing value.

 

 

3

Rotate the front panel Voltage knob to obtain 120 V. This method is best when you
